Given AABE~ ADCE and BC intersects AD at E, what is the value of y
Answer:
Step-by-step explanation:
The value of y is unclear given the information provided. However, if BC intersects AD at E, then it stands to reason that y would be equal to the value of x. This is because, if BC intersects AD at E, then the two lines are parallel and therefore have the same value for y.
The vertex form of the quadratic function f(x) = x² + 10x + 1 is f(x) = a(x - h)² + k.
What is the value of a? |
What is the value of h?
What is the value of k?
Answer:
[tex]a=1, h=-5, k=-24[/tex]
Step-by-step explanation:
[tex]f(x)=x^2+10x+1 \\ \\ =x^2+10x+25+1-25 \\ \\ =(x+5)^2-24 \\ \\ \therefore a=1, h=-5, k=-24[/tex]
How do you solve a system of three equations in two variables?
Pick any two pairs of equations from the system. Eliminate the same variable from each pair using the Addition/Subtraction method. Solve the system of the two new equations using the Addition/Subtraction method. Substitute the solution back into one of the original equations and solve for the third variable.
In order to solve systems of equations in three variables, known as three-by-three systems, the primary goal is to eliminate one variable at a time to achieve back-substitution. A solution to a system of three equations in three variables (x,y,z) is called an ordered triple.
To find a solution, we can perform the following operations:
Interchange the order of any two equations.Multiply both sides of an equation by a nonzero constant.Add a nonzero multiple of one equation to another equation.Graphically, the ordered triple defines the point that is the intersection of three planes in space. You can visualize such an intersection by imagining any corner in a rectangular room. A corner is defined by three planes: two adjoining walls and the floor (or ceiling). Any point where two walls and the floor meet represents the intersection of three planes.

The amount of water added by the pool maintenance to make the pool 90% full is 178,200 gallons.
How much water, in gallons, did they add?The amount of water an Olympic-sized pool can hold is, 660,000 gallons.
The pool is 63% full at the moment
The of water in the pool now is:66% of 660,000 gallons
If the pool is 90% full then the amount of water in the pool is:
90% of 660,000 = 594,000 gallons
The amount of water added by the pool maintenance is:
Amount of water added = 90% of 660,000 - 63% of 660,000
594,000 - 415,800
= 178200
Thus, the amount of water added by the pool maintenance to make the pool 90% full is 178,200 gallons.

For the given statement f(x)= a(x-h)² + k is the vertex form of a parabola.
If a < 0, h> 0 and k < 0 Option B is correct.
Vertex of a Parabola
The vertex of a parabola is the point where the parabola crosses its axis of symmetry. If the coefficient of the x2 term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the “ U ”-shape. If the coefficient of the x2 term is negative, the vertex will be the highest point on the graph, the point at the top of the “ U ”-shape.Given that:
f(x)= a(x-h)² + k
If a < 0, h> 0 and k < 0 then
f(x) = -1 (x - 1)^2 - 1
= -1([tex]x^{2} + 1^{2} - 2x[/tex]) - 1

find the length of the arc of the curve from point p to point q. x2 = (y − 4)3, p(1, 5), q(8, 8)
The length of the arc of the curve from point p to point q of the equation x2 = (y − 4)3 as calculated is 8 units.
as to calculated the length of the arc we will differentiate the given equation x² = (y-4)³ with respect to y
=> 2x = 3( y - 4 )²
=> 2x = 3( y² -8y + 16)
=> 2x = 3 y² - 24y + 48
=> 3 y² - 24y + 48 - 2x = 0
now , x = 5 - 1 = 4
y = 8 - 1 =7
Therefore, length = 3 x 8² - 24 x 8 + 48 - 2x 4 = 0

The correct answer is c.) the probability of getting a number less than 3 is equal to 0.33 but does not change the probability of the next trial.
The probability of getting a number less than 3 on a standard die is always equal to 0.33, regardless of the number of times the die is rolled. The probability of an event occurring does not change based on the number of times the event has occurred in the past. Each roll of the die is an independent event, meaning that the outcome of each roll does not affect the probability of the next roll.
